Cartridge Repair and Replacement

Faucet cartridges (Cartridge Repair) regulate the water pressure and temperature that flows through the faucet’s spout. The faucet may have a single or double handle, depending on the model. The cartridge component of a single-handle faucet is housed within the stem or body. A leaky faucet is a common problem every house faces at times.

There are several reasons for the leakage of the faucet cartridge. There are mainly two types of faucet cartridges i.e. single-handled and two-handled and different models employ different types of plastic or brass-body cartridges.

Shower Faucet Cartridge Replacement

To start and stop the flow of water, the handle of a single-handle faucet elevates or lowers the cartridge within the faucet body. Both hot and cold water flow into the same cartridge, and the combination and temperature are controlled by turning the handle. Two-handle cartridge faucets work similarly to single-handle cartridge faucets, but there are two cartridges in this design, each regulating the flow of hot or cold water. Instead of pulling the cartridge up and down, the handle twists it. We will discuss the causes of leaky cartridge faucets, the tools & material needed to fix them, and the method to solve this problem.

Issues with cartridge (when cartridge doesn’t work properly)

  • O-Ring failure.

    One of the main causes of the leaky faucet is the issue with the O-ring. The failure of the o-ring may cause water to leak.

  • The cartridge is damaged.

    If the cartridge is damaged and it does not work properly, water leakage may result.

  • Valve Seat Corrosion

    Corrosion of the valve seat can also cause a leaky faucet.

  • Washers that have worn out.

    The washer may be damaged and worn out after several years of use which may result in a leaky faucet.

  • Seals that have worn out.

    The seals of the cartridge may get damaged after a long period of usage or other reasons which may cause the leakage of the water.

  • Pressure of water

    The leakage may result due to the high water pressure in the pipeline. High water pressure may damage the cartridge.

  • Loose Parts

    The faucet cartridge components may get loose due to excessive use or defects that may result in water leakage.

Cartridges can be found in:

  • Faucet
  • Kitchen Sink
  • Bathroom Shower

How to identify Cartridge brand?

It is the easiest when the brand name is printed directly on the faucet face. Examine the faucet’s bottom, handles, and the circular plate behind the handles, though. If you come across a brand name, visit the manufacturer’s website and ask for help.

Ways to Fix Leaky Faucet Cartridge

If the problem is not complicated, you can fix the leaky faucet on your own. Before starting the fixing process, you must identify the problem. The faucet cartridge is used in different parts of the household. We will discuss the method to fix the leaky cartridge

  • Remove the handle

Firstly, remove the handle of the faucet by rotating it.  This can be difficult since the screw that keeps the handle in place is typically hidden under a detachable plastic cover plate or cap. This cap can be located on the top of the handle, on the sides, or on the side of the faucet handle body as an exposed Allen-head set-screw.

  • Unscrew the faucet

Based on the faucet model, the cartridge will be kept in place in a different way. In most circumstances, it will be secured in place within the faucet body by a retaining nut. When the handle is removed from an older, simpler faucet, the cartridge is held in place by a big nut.

  • Take off the trim sleeve

Pull The trim sleeve that covers the cartridge. The trim sleeve depends on the faucet model.

  • Remove the bonnet nut

After pulling off the trim sleeve, unscrew the bonnet nut. Bonnet net depends on the model. You can unscrew  some bonnet nuts with your hands whereas some need a strap wrench. Rotate the bonnet nut counter-clockwise.

  • Pull the cartridge

A cartridge retaining clip is found on some faucets. Remove the clip with care and pull the cartridge. In some cases you may need a puller. In this case, follow  this process:

  • Fix a puller to the cartridge
  • Tighten the puller to the cartridge
  • Rotate the puller
  • Pull the cartridge
  • Install a new cartridge:

Replace the cartridge with a fresh one. The new cartridge is straightforward to install; just make sure it’s correctly aligned as it goes in. Apply a light layer of heatproof silicone plumber’s grease to all rubber O-rings and rubber seals on the cartridge.

  • Reassemble the component of the faucet:

If the cartridge tabs were not perfectly aligned with the retaining clip notches, you may need to rotate the cartridge a little to get the clip firmly inserted. It should click into place if you rotate the cartridge slightly while putting the clip into place with the white plastic tool.

I called Everest Plumbing the day after a crazy storm because my sump pump stopped working. Nimesh came the same day and replaced my sump pump quickly and efficiently. Afterward he was very responsive by text and phone when I had concerns because the pump was running constantly. He even came back on a Saturday morning (his day off) to re-examine it. By that time it was functioning perfectly because he was right - it had been running because of the high water table. Excellent service and follow up!

I had a huge problem with a backup sewer back on March 2026. I called a major Canadian plumbing company who came over chaged me $360 to put a camera in the pipe. The guy the whole time criticized the drainage system. He suggested that I break the whole basement and replaced the sewer line. He pushed for me to sign a contract that would cost twenty thousand. I didn't feel comfortable with his attitude. I had never had problems for 15 years. I began to look for another company, then I new it would cost me more money to put the camera again. So I called back the company to file a complaint. The secretary told me she would send the supervisor over, which she did. He was very nice, put the camera again and told me the problem was outside the house. He told me the pipe was broken and uneven, which was causing the problem. I couldn't understand how a PVC pipe could have been broken since it was done around 2010 and 2015. Since the backup was smelling really bad in the house I agreed to pay for their service. What he didn't tell me that the problem was on the city side of the property. They were dishonest and took advantage of my situation to charge me a lot of money and didn't solve the problem. 4 months later, I had the same problem. I called back the supervisor who told me he was busy and would return the call later and never did. The is when I called Everest Drain &Plumbing company. Suraj came over, put the camera in the sewer he showed me the same broken pipe the other company had showed me. He then told me the problem was on the city side and I should contact the city. I called the city right away while he was still here. He helped me by speaking with the city and explained the situation which was urgent. Suraj was extremely helpful, honest and cordial. I am so grateful for his service and honesty. Should I have any plumbing issues I will definitely call Everest Drain & Plumbing company again. Thank you Suraj.

Big thanks to Mr. Nimesh. He really saved me and my home from almost flooding the basement. Nimesh was quick to snake the blocked drain, and later, with his camera inspection, he found that the blockage was caused by roots. He snaked and cleared out the roots. Everything is now working completely fine, and he showed his work through a camera inspection proving the roots were cleared after the snake. A big thank you to Mr. Nimesh for helping to calm down such a panic moment.

First time working with Everest. Great experience! Was able to get a next morning appointment to fix our leaking sink. Plumber arrived on time, analyzed the problem, replaced a part, cleaned out the drain, tested everything, and cleaned up. The price was reasonable. Our new go-to plumber when we need one (not too soon please😉) Highly recommended.

Found Everest on Google after looking for someone to clean our drain line. Rajiv and Sandip appear as a team; their housekeeping was excellent. They cover and protect every aspect as needed. The work performed was clean and swift. They did power flushing until all the debris was clear time and again. Impress with their dedication toward work. Great team, will use them again in the future.

Great Drain Cleaning and Flushing Service by Tenzin and Mr. Sandip, who well-communicated and was professional about all the work he did. Housekeeping was top-notch, from bringing tools in to keeping tools properly while working. Everything was smooth from beginning to finish. No mess; leave the house as it was after completing snaking and flushing.

I had a great experience with this company. They were very professional and arranged for a plumber to come out quickly. Nimesh did an excellent job resolving my plumbing issue. He was professional, friendly, and patient throughout the entire process. He took the time to explain everything clearly and made sure the problem was fully resolved. I truly appreciate the excellent service and would highly recommend both Nimesh and the company to anyone looking for reliable plumbing services.

Tenzin came to fix a sump pump and check valve issue after a massive rainstorm. He worked hard to diagnose the complex problems and trial a few different solutions that fit the unique aspects of my house and property. His demeanour was very kind and calm and it was a pleasure to have him in our house. Great work!

Excellent service from Everest Drain & Plumbing. They are a family-owned business and Indra arrived promptly for a service call on the weekend, even though he works weekdays, to fix my clogged drain. They were very efficient and courteous. Indra assessed the situation in a timely manner and fixed the issue quickly without making any mess. Definitely knows his work, and I highly recommend them if you're looking for a local plumber. Thanks, Indra. Great work!!!

I had a pipe burst a few days ago and contacted several companies, but Everest Drain and Plumbing was the only one that could clearly confirm how soon they could attend to the issue. They offered me a 9:00 AM appointment the following morning and arrived right on time — even a bit early. I truly appreciated the prompt response, professionalism, and fair pricing. The service was efficient, and everything was handled smoothly. I would definitely choose Everest again for any future plumbing needs. Thank you, Everest, for your excellent and reliable service!

I had a pipe burst a few days before Christmas - tis the season. Out of the companies that I contacted, Everest was the only company that could confirm how soon they'd be able to attend to the issue. They offered an appointment for 9am the following morning and Indra was prompt, if not early. We were very appreciative with his service, and I would go directly with them for future plumbing issues/needs. Thank you Indra and Everest for your prompt service and pricing.

Our main drain was cracked. From the moment we called Everest Drain the service has been exceptional. Indra was very professional and honest, the work they performed was very clean as they had to dig a finished basement. They did not make a mess and finished the job on time. I have no hesitation in recommending this company.

I recently had the pleasure of working with Everest Drain & Plumbing in Toronto, and I could not be more impressed with their exceptional service! From the moment we called them for assistance with plumbing work, I knew it was in good hands. Aly was punctual, with something we always appreciate. Not only professional but also incredibly knowledgeable about the problem. He explained in detail and made me understand before moving forward. The work was completed with the highest level of craftsmanship. One of the standard aspects of Everest Drain & Plumbing is their fair and upfront pricing. The pricing was reasonable for the quality of work provided, and I appreciated their transparency. What truly sets them apart is their outstanding customer service. Aly made sure to clean up after all the work completed, and there were no surprises when the work was done. I was overall impressed by how well Aly managed the entire process from diagnosing to resolution. If you are looking for a trustworthy, skilled and professional Plumbing company look no further. They have earned a loyal customer in me!
